Chapter 2: AM713 and MA703 Converters
Features
Professional grade audio conversion is accomplished utilizing
128 times over-sampled noise-shaped delta-sigma techniques.
The analog to digital conversion employs a multi-bit modular
architecture while the digital to analog conversion employs a
single-bit modulator architecture. Low-jitter reference clocks
are provided utilizing digital PLL techniques with VCXO and
VCO oscillators.
The analog inputs and outputs can be calibrated from the
front panel of each unit. Four segment LEDs on the front
panel monitor signal level. LED meter segments indicate -42,
-18, -6 (green) and -0.005 dBFS (red).
AES/EBU and Word Clock external sync inputs on both units
provide synchronization to digital systems. Sample Rate
Source and Sample Rate are automatically sensed by both
units. Supported sample rates include 44.1, 48, 88.2, and 96
kHz. In addition, pull-up and pull-down rates for the standard
sample rates, as well as custom sample rates are available.
Applications
In addition to their standard use in a Pro Series digital system,
the AM713 and MA703 can be used as stand-alone converters
when 24, 48, or more channels of analog-to-MADI and/or
MADI-to-analog conversion is necessary (i.e., interfacing an
analog tape deck to a digital mixer). When used with the
SH612 Studio Hub, this is a powerful conversion and MADI
routing system that can be used as an interface between an an-
alog console and an otherwise all-digital facility (i.e., TV
broadcast facility).
MADI cables can be extended to 50 m (164 ft),
allowing remote location of the converters.
